An automatic zone detection system for safe landing of UAVs

作者：

Highlights：

• The proposed systems explore different Gabor orientations for locating flat regions.

• Candidate pixels are detected for flat regions with uniform Gabor orientations.

• The Markov Chain Code process is used in a new way for groping candidate pixels.

• The Chi square similarity measure has been used for finding safe landing zone.

• The proposed system outperforms the existing systems in terms of recall, precision and F-measure.
